The true definition of "gonk" is when you backhand a guy right in the nuts. Saying the word "gonk" at the same time is required. The word gonk is used by only the best of all backhanders. Are you the best?

The script you follow:
You - (Backhanding the guy becide you) "GONK!"
Other Guy - "Aww fuck. What the hell was that for?"

"I gonked that other guy the other day."
"Lets have a truce. No gonking eachother."
